CodeIgniter: загрузить видео на YouTube

Я не рекомендую использовать Zend с CI из-за его размера и сложности. Я разработал библиотеку специально для CodeIgniter https://github.com/jimdoescode/CodeIgniter-YouTube-API-Library

Библиотека предоставляет несколько различных вариантов загрузки на YouTube. Вы можете сделать прямую загрузку, когда вы загружаете видео, хранящееся на вашем сервере, на YouTube. Также есть возможность использовать форму для загрузки видео с клиента на youtube. Проверьте это и дайте мне знать, если у вас есть какие-либо вопросы.

Попробуйте это работает
